Having just replaced the PVC valve on a 2013 TSI and still getting a P2177 code I started looking for vacuum leaks and would like to know if it is normal for a good PCV valve to expel a small amount of air through the vent hole?

That won't tell you were the leak is (unless it's huge and you can hear the air getting back into the system), but it will tell you if you have one, and it will also give you an idea of the size of the leak (by how fast the vacuum is lost).

This could be cause by a small vacuum leak or by a dirty air filter or mass airflow sensor (MAF).

So if you have black smoke, it can be an air / vacuum leak, VGT valve, exhaust pipe, etc..

If I removed this air pump and shut off valve, the vacuum line would be open, which I think may cause vacuum leak.

You might also check vacuum lines and intake manifold gasket for air leaks.

This means there is more air than usual such as a vacuum leak or EGR opening up when it's not supposed to.

Start a vacuum - leak smoking expedition by plugging up any obvious potential ports in the intake manifold, starting with the inlet to the throttle body from the air cleaner.

A leaky manifold gasket can also result in air being sucked through the leaky gasket, resulting in a vacuum leak and poor engine performance.

Common faults would be the faulty throttle body, throttle body linkage, fuel restriction, vacuum leak, idle air valve, or...

If there is no vacuum leak, then check the idle air control valve (IAC) and see if it's...

A vacuum leak from items like a broken air intake boot, broken / disconnected vacuum lines, or a leaking intake manifold gasket can lean out the air / fuel mixture or disturb intake airflow enough to...

The problem sounds like you either have a massive vacuum leak or a problem with the idle air control valve.

A vacuum leak can cause an engine to idle high due to the excessive amount of air flow into the fuel injection system.

If this issue it only occurring at idle, then it is either due to a vacuum leak in the engine or more commonly a failing idle air control valve.

Stalling at idle could be due to a faulty mass airflow sensor, faulty camshaft or crankshaft position sensors, worn spark plugs, wires or defective ignition coil (s), inadequate fuel delivery or pressure (clogged fuel filter, injectors, faulty fuel pump or pump circuit), contaminated or old gasoline, defective throttle position sensor, faulty idle air control valve, leaks in the EGR system, intake vacuum leaks, and so forth.

In a more technical jargon, vacuum or intake leaks are called «unmetered air», as the air enters the intake system through a damage intake boot or other leak is not metered by the mass air flow sensor and therefore the the engine computer can not calculate the amount of fuel injected properly, causing the engine to run «lean».

An air leak anywhere between the engine intake and the air filter is usually called vacuum or Intake leak.
